Based on your experience using pc monitor which cable is the best for both gaming and movies?

1) DisplayPort

2) HDMI

3) DVI

4) VGA
I will using Dell u2412m with nvidia geforce gt240

So which is better based on your experience but no need to based on my pc spec, you can add your own

I totally confused because someone said HDMI is better than DVI but suddenly they said DisplayPort is much better than these two

But in term of gaming and movies, it still hard for me to select the best one
